Comparing cumulative index and factor analytic approaches to measuring maltreatment in the National Longitudinal Study of Adolescent to Adult Health     

《Child abuse & neglect》2019

Child maltreatment is a complex and multifaceted construct in need of advanced statistical techniques to improve its measurement. The current study compared the predictive utility of a cumulative index to a factor analytic approach for constructing a measure of maltreatment. Data were from Waves III and IV of the National Longitudinal Study of Adolescent to Adult Health (Wave III: n = 14,800; Wave IV: n = 12,288). As adults, participants retrospectively reported on their childhood experiences of physical abuse, sexual abuse, emotional abuse, physical neglect, supervisory neglect, and social services investigations. Both the cumulative index and a two-factor solution showed evidence of convergent validity, predicting lifetime incidence of homelessness, being paid for sex, and various measures of running away or living apart from biological parents, and prospectively predicting depression, substance use, and criminal behavior. The latent variables, derived from a factor analytic approach, had greater explanatory power for many outcomes compared to the cumulative index, even when controlling for sociodemographic variables. Results suggest that factor analysis is a better methodology than a cumulative index for measuring maltreatment in large datasets when explanatory power for external outcomes is of greatest concern.  相似文献

公共产品理论视野下图书馆产品的生产与供给问题研究   总被引：7，自引：0，他引：7  

熊伟 《图书馆杂志》2005,24(4):9-13

图书馆产品的本质属性是准公共产品。其生产可不以营利为目的，也可以营利为目的；可由政府投资，也可由社会力量投资；可采取公共生产方式，也可采取非公共生产方式；可实行事业型生产，也可实行产业型生产。公共供给、市场供给和混合供给是图书馆产品供给的三种基本方式。混合供给方式较之公共供给方式和市场供给方式有更高的效率。图书馆产品生产与供给有多种组合方式。  相似文献   

Manufacture and Date of a Goryeo dynasty Sutra Box with Mother-of-pearl Inlaid Decoration at the Rijksmuseum,Amsterdam     

Nanhee Lee 《文物保护研究》2018,63(3):163-170

Currently, about ten Goryeo dynasty (918–1392 CE) sutra boxes are preserved in museums in Korea, Japan, the United States, the Netherlands, and the United Kingdom. This article is the result of an examination of a sutra box in the collection of the Rijksmuseum, Amsterdam (hereafter ‘Rijksmuseum sutra box’), which was first introduced to a European audience in the Transactions and Proceedings of the Japanese Society, in 1913–1914. The Rijksmuseum sutra box differs from other Goryeo sutra boxes. With its altered structure and modified motifs, this box bears significant value, not only for the research of thirteenth-century Goryeo mother-of-pearl art, but also for the study of cross-cultural adaptations in East Asian lacquer art. This article investigates the date of manufacture of the sutra box by analysing the manufacturing techniques and its various original and modified parts. For this, an X-ray radiograph was carried out for the first time. As a result, discoveries have been made regarding the structure and decoration of the lower part, which has been modified and is different from Goryeo mother-of-pearl sutra boxes. Finally, this paper reconsiders conservation and repair of Goryeo sutra boxes, as illuminated by an understanding of the original and repaired parts of this box.  相似文献

英国工业革命期间的社会立法     

赵虹 《云南师范大学学报(哲学社会科学版)》2002,34(6):38-42

在英国步入“福利国家”的历史进程中,各项社会立法的提出、确立、不断完善是其主要途径之一。其中,在英国工业革命期间的几项社会立法无疑处于这一社会立法轨迹中的起始阶段,有其渊源关系。其他位和作用应予以肯定。  相似文献
